Temporary binding repair

Last weekend the rubber (or neoprene or whatever they make them out of) on one of my bindings split between the ankle and the heel. I'm looking at getting some new bindings but until I can find a real deal on some, I'm trying to make due with what I have. Is there any epoxy or something along those lines that I can use to patch things up that will hold up for a little while? What material are the wraps on the bindings made of (specifically CWB Comps)? I really don't want to break out my Liquid Force Sandals.
